CHAPTER 4
POWER REQUIREMENTS
The Sauermann SI-AQ VOC Indoor Air Quality Monitor is a battery-operated Portable device
designed to be operated by a qualified engineer/technician to make measurements in buildings and
residential facilities. For long-term testing please carefully follow the product safety instructions in
Chapter 1.
Power is supplied by a Li-Ion rechargeable battery pack. The battery pack will supply power to the
monitor for about at least 8 hours of continuous operation.
A 110 – 240 Volt AC charger having a 12 Volt DC / 2.5A output is supplied with the instrument. The
battery charger will fully charge the battery pack in three hours.
You can check the condition of the batteries at any time:
1.
By pressing the
MEASURE
key, (small font screen) and observing the battery icon, located at
the bottom of the display.
2.
By pressing the
MEASURE
key, (large font screen), the user can scroll all the way to the
end using the
DOWN
arrow key to observe the battery life shown in Voltage. When the
unit is operating on its internal batteries, the voltage displayed will vary from an initial 8.0 to
8.4 volts (fully charged) dropping slowly to approximately 7 volts (batteries nearly empty).
When the battery voltage drops to 7.1 volts a “low battery” warning will appear on the
display. Within a few minutes later the instrument will automatically turn off, to preserve the
remaining battery power for the sensor bias voltages.
